Specification of Letters Patent.

Patented Dec. 22, 1191.4.

, Application filed February 20. 1914. Serial No. 819,915.

To all whom it may concern:

Be it known that I,'LoUIs Scnonnme, a citizen of the United States, anda resident of the city of Chicago, county of Cook, and State ofIllinois, have invented certain new and useful Improvements in Pliers,of which the following is a specification.

My invention relates to improvements in pliersand has for its object theproduction of a device of this character in which the. levers may berelatively shifted in order to adapt the device for use for inside oroutside gripping.

A further object is the production of a pliers as mentionedwhich will beof durable and economical construction and eflicient in use.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of partshereinafter described and claimed.

The invention will be best understoodby reference to the accompanyingdrawlng forming a part of this specification, and in which- Figure 1 isa side elevation of a pliers embodying my invention, the plier leversbeing adjusted to adapt the same for outadapt the same for insidegripping, and.

side gripping. Fig. 2 is a view similar to ig. 1 showing the plierlevers shifted to Fig. 3 is a section taken on line aw of Fig. 2.

The preferred form of construction as illustrated in the drawingcomprises a pair of similar levers 1 and 1, said levers being pivotallyconnected intermediate their ends by a fulcrum pin 2. Said fulcrum pinengages slots 3 and 3 formed 1n said levers 1 and 1' respectively. Saidslots are elongated, the elongation being in a direction transversely ofthe levers, and said slots are of the keyhole type, that is enlarged attheir opposite ends for cocperation with the pin 2 which is flattened atits opposite sides. With this arrangement it will be seen that saidlevers may be unlocked to permit of relative shifting or locked inpositions of relative shifting by simply rotatably adjusting said pin,it being clear that, when said pin is in engagement with the enlargedends of slots 3 and 3 and positioned transversely relative to the narrowcentral portions of said slots, as shown in Figs; 1 and 2, said leverswill be locked in positions of relative shifting and when said pin isadjusted to position the flat sides thereof in alinement with the narrowcentral portions of said slots, movement of said pin in said slots andhence relative shifting of the levers is permitted.

Said slots are of such lengths that said levers may be shifted to aposition in which the same cross each other at the fulcrum point asshown in Fig. 1 or in which said levers extend substantially parallelwith each other in spaced relation as shown in Fig. 2. I11 the firstposition of said levers it will be seen that the device constitutes anoutside pliers whereas when said levers are shifted to theposition'shown in Fig. 2, the device constitutes an inside pliers.

The fulcrum pin 2 is provided at one end with a head as shown and at theother end thereof is provided a collar 4 which is locked in position bya cotter pin 5. Provided upon the head of pin 2 is a spring finger 6 theouter end of which is bent inwardly to adapt the same to releasablyengage recesses or depressions 7 and 8 provided upon the outer side oflever 1 in order to releasably lock said pin in looking positionrelative to the slots 3 and v3 as will be readily understood. Saidspring finger also facilitates rotative adjustment of the pin 2 ineffecting looking or unlocking of the levers 1 and 1.

.adapted to perform the double function of inside and outside pliers andin which the shifting of the plier levers so as to adapt the same forservice in either capacity may be readily and easily effected.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without departing from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suchvariations and modifications as come within the scope of the appendedclaims.

Having described my invention what I claim as new and desire to secureby Letters Patent is: A v

1. A device of the class described comprising a pair of levers; afulcrum pin pivotally connecting said levers, said levers be- I ingprovided with slots for engagement by said fulcrum pin, said slots beingelongated in a direction transversely of said levers, whereby saidlevers may be relatively shifted, said slots being of key-hole formationand said pin being flattened whereby said levers may be locked in positions of relative shifting 'or unlocked to permit of shifting adjustmentby rotatably adjusting said pin; and a resilient finger on said pinadapted to engage recesses in one of said levers for releasably lockingsaid pin in positions of rotative adjustment, substantially asdescribed. a

2. A device of the kind described comprising a pair of levers, eachhavin a lateral ear thereon and each ear over ap ing the other ear,there being a slot in each ever extending laterally thereof into the earof such lever and the ends of said slots being enlarged; a pin disposedthrough the slots of said levers, said pin when in the enlarge- .name tothis specification in the presence of two subscribing witnesses.
